Support address group in OVS firewall agent
Support security group rules with remote_address_group_id in openvswitch firewall. This change reuses most of the firewall functions handling remote security groups to also process remote address groups. The conjunctive flows for a rule with remote_adress_group_id are similar to others with remote_group_id but have different conj_ids. Change-Id: I8c69e62ba56b0d3204e9c12df3133126071b92f7 Implements: blueprint address-groups-in-sg-rules

features:
|

- |
|
||||
A new API resource ``address group`` and its CRUD operations are introduced
|
||||
to represent a group of IPv4 and IPv6 address blocks. A new option
|
||||
``--remote-address-group`` is added to the ``security group rule create``
|
||||
command to allow network connectivity with a group of address blocks. And
|
||||
the backend support is added to the ``openvswitch`` firewall. When IP
|
||||
addresses are updated in the address groups, changes will also be reflected
|
||||
in the firewall rules of the associated security group rules.
